Possibility of a new approach to processing space pulse radio signals
A approach to the processing of space pulse radio signals, which makes it possible to achieve a high level of time resolution is proposed. The approach is based on the utilization of the Fourier transform of a radio pulse envelope in the interstellar medium effect. The conditions of applicability of the proposed method and the requirements for recording equipment are substantiated. Also indicated is the possibility of obtaining superresolution with the utilization of the given method of signal processing
Branching Brownian Motion with catalytic branching at the origin
We consider a branching Brownian motion in which binary fission takes place
only when particles are at the origin at a rate \beta > 0 on the local time
scale. We obtain results regarding the asymptotic behaviour of the number of
particles above \lambda t at time t, for \lambda > 0. As a corollary, we
establish the almost sure asymptotic speed of the rightmost particle. We also
prove a Strong Law of Large Numbers for this catalytic branching Brownian
motion.Comment: 25 page
